Problem

Equal masses (

0.50\,\text{g}

each) of

^{235}\text{U}

and of an equimolar

^2_1\text{H}

–

^3_1\text{H}

mixture are completely used as fuel. The D–T fusion releases

17.6\,\text{MeV}

per reaction, while

^{235}\text{U}

fission releases

200\,\text{MeV}

per reaction. Which statement best describes the energy yield? (a) The D–T mixture yields about

4

times more energy than

^{235}\text{U}

(b)

^{235}\text{U}

yields about

11

times more energy than the D–T mixture (c) Both fuels yield nearly the same total energy (d) The D–T mixture yields about

8

times more energy than

^{235}\text{U}
